[Dxspider-support] MRTG graph for RBN spots

[Keith Maton]

Hi Uli,

That would be great, thanks.  I don’t know anything about perl so I’m just going to nod and agree with you :-)

It would be good to see the number of skimmer spots on an MRTG graph and if the amount of spot data in/out could be plotted as well, that would be even better.

That’s an interesting view of the log as well, thanks.  

Very keen to see how you get on.
